Spray Pretreatment Powder Spray Coating Line System Custom

Coating pre-treatment product before spraying process collectively, the conventional visible for degreasing rust and phosphate processing. Spray pre-treatment, as the name implies, is the use of high-pressure spray to phosphated metal components in the factory store, transport or machining of the workpiece, oil, rust formed in the surface layer (oxide), etc. . If the direct coating of the coating attached to these artifacts not only affect the coating adhesion, appearance, moisture resistance, corrosion resistance, and corrosion under the coating film to spread, resulting in the defects of the coating film peeling, blistering, even coating into a piece off. Therefore, only prior to coating, the workpiece surface oil, rust, or oxide, sand, welding slag, palmar attachments divisible, in order to prevent the coating blistering, loss and other undesirable phenomena occur, in order to improve the coating film adhesion and corrosion resistance.

Pre-treatment process purpose

(1) provides a clean surface;

(2) can significantly improve the adhesion of the workpiece surface;

(3) can exponentially increase the corrosion resistance of the coating;

(4) can improve the flatness of the workpiece surface and the decorated

(5) create a good base for painting.

Pretreatment process

?Loading workpiece → degreasing spray (40-50 ° C 3.0min) → drip → the washing spray (RT 1.0min) → drip → washing spray (RT 1.0min) → dripping → Table tune spray (RT 1min) → drip → phosphating spray (35-45 ° C for 3 min) → drip → washing spray (RT 1.0min) → drip → washing spray (RT 1.0min) → the water dripping → drying (100-120 ° C 15 in) → spraying

?Pre-treatment requirements and configuration;

1)?full spray treatment process, the rational use of production sites.

2)?washing spray the reverse cleaning method, both to improve the quality of cleaning and water conservation.

3) spray the top of the shed body has a high temperature sealing brush and exhaust devices, you can prevent gas channeling outside rail and chain protection against corrosion. Spray process between segments are set isolated flap to reduce the phenomenon of channeling liquid between the process section.

4)?sprinkler riser using a pressure regulating device, the atomizing nozzle output is more stable.

5)?sprinkler riser connected with the competent fast-loading, maintenance, easy to install.

6)?spray the top of the shed body has a gantry bracket is a spray shed body ribs, hanging rail supply tube mount.

7)?Each sump with overflow tank and outfall, sewage clear slot is very convenient.

8)?nozzle to use environmentally nozzle.
